External Enzymes Research Directory
Where internal enzymes maps a science, this page maps an industry with a science attached. When a gluten-free malt cannot deliver the enzyme activity a recipe needs, the working answer across the industry is a measured addition from an industrial producer. That layer has its own research world — application studies, process integration, raw-grain brewing where an enzyme package replaces malting entirely — and almost none of it overlaps with the university malting science the grain directories map. This page charts it honestly: described, never endorsed.
Where this site stands, so the map is read honestly: for Gluten Free Brewer, external enzymes own conversion — this is the wing our own process design runs on, and our working pages document specific products in actual use. This directory maps the wider world around that position; a listing here remains a map reference, not a recommendation, and GFB holds no financial interest in any enzyme product or supplier.
Coverage is US-centered by design — this site works in the American supply chain — with international anchors included where the science or the suppliers are foundational; industrial enzyme production is a global business by nature.

Key topics — find entries by subject, across every category
How to read it: each topic lists the entries that touch it, so a reader hunting one subject can jump straight to the right sections.
The products & their makers — Suppliers & Industry: the producers, the distributors, and the enzyme classes they sell.
The application science — the raw-sorghum brewing corpus (Literature), Heriot-Watt and the classic bench (Institutions, Contributors).
The rules — Regulation & Labeling: GRAS notices, TTB approvals, and the processing-aid question.
The boundaries — where the enzyme world touches what this site doesn't brew: barley-conversion products and gluten-reduced processing (Regulation, How the field connects).
1. Institutions — the labs and universities doing application research on added enzymes
An honest note first: most external-enzyme science is done inside the producers' own laboratories and published as technical sheets rather than papers. The university layer below is real but thin — the academic homes of the application studies this page's literature carries.
Heriot-Watt University — Edinburgh, Scotland. The academic home of the classic bench: the commercial-enzymes-on-sorghum-wort studies of the 1990s came from the brewing school here — the application literature's founding institution. The study record · Verified 2026-08-25
University College Cork — Ireland. The Arendt group again — this time on the added side: the unmalted-sorghum mashing studies with commercial enzymes, and the 50%-unmalted-sorghum pilot lager, are the bridge between this wing and the family's malting science. The mashing study · Verified 2026-08-25
Łódź University of Technology — Poland. The pseudocereal application bench from our quinoa page: unmalted quinoa brewed with a commercial enzyme mixture — the added-enzyme route tested on the family's newest grains. The study · Verified 2026-08-25
University of Bamenda / ENSAI — Cameroon. Desobgo's response-surface modelling of commercial enzyme doses on unmalted sorghum — the optimization mathematics of the added-enzyme mash, from the researcher on our sorghum directory. The modelling study · Verified 2026-08-25
University of Birmingham — England. The School of Biochemistry where the full-replacement question was answered: Bajomo & Young's 1992–1994 raw-sorghum trilogy ran here — profile, extract, and fermentation, entirely on added enzymes. The trilogy's close · Verified 2026-08-25
University of California, Davis. The US academic home of brewing enzymology: Bamforth's endowed malting-and-brewing chair carried the process-enzyme corpus — including what added glucanases and proteases do in a working brewhouse — for two decades. The chair's profile · Verified 2026-08-25
University of Pretoria — South Africa. The tropical-cereals school on this wing too: Taylor's reviews document the enzyme-supported African industrial lager practice — the largest working example of added-enzyme brewing on a gluten-free grain anywhere. The review, open · Verified 2026-08-25
University of Nigeria, Nsukka. The named unit this wing was missing: the Brewing Science and Technology Unit in Nsukka's microbiology department — Okolo's group — carries the modern Nigerian corpus, from the 2016 malted-plus-enzymes study to the 2020 sugar-balance work. The 2020 study, open access · Verified 2026-08-25

The industrial-research institution shared with our fonio directory: the laboratory founded in 1875 and Carlsberg Foundation-funded — the birthplace of pH and Kjeldahl nitrogen — now brewing the alternative grains this family maps. The laboratory · Verified 2026-08-25
Penn State University. The four-directory brewing program on this wing's side of the ledger too: its modified mashing procedure operates in the enzyme-supported gluten-free space this page maps. The program's study · Verified 2026-08-25
Federal University of Rio Grande do Sul — Brazil. The one grant-funded academic program currently working this wing: Porto Alegre's food-science institute, applying enzymes across brewing stages under numbered national grants — see Projects. The funded work · Verified 2026-08-25
A federal note: we have found no US federal laboratory running added-enzyme brewing research — the federal presence on this wing is regulatory, and it lives in Regulation & Labeling below.
2. Contributors — the researchers behind the application science
Declan Goode & Elke Arendt. The UCC pair behind the unmalted-sorghum corpus: mashing studies with commercial enzymes (2002), optimization work, and the pilot-scale 50%-unmalted-sorghum lager (2003) — the most complete academic treatment of enzyme-supported gluten-free-relevant brewing we have found.

The Ndubisi study team. The Nigerian bench's modern entry: malting time, mashing temperature, and added commercial enzymes on a yellow sorghum, combined in one JIB study. The study · Verified 2026-08-25
3. Projects & Grants — funded work in flight, and the asks awaiting it
What qualifies: funded or actively developed work with public output on added enzymes in gluten-free brewing. This site's open research asks are not projects — they live in Research gaps, where unfunded questions belong.
The Penn State program (funded, active). The four-directory gluten-free brewing program on this wing's projects too: its funded modified-mashing work operates in the enzyme-supported space this page maps. The program's study · Verified 2026-08-25
Mash Protocol 3 development (ours, active). This site's own open protocol project: the proposed maltose mash — an enzyme-sequence redesign toward a conventional wort profile — developed in public on its own page. Disclosed as ours. The proposal · Verified 2026-08-25
The UCC unmalted-sorghum program (completed, corpus standing). The 2002–2003 Cork campaign — mashing studies, optimization, the 50%-unmalted pilot lager — a completed program whose corpus is still the wing's academic backbone. The pilot · Verified 2026-08-25
The Birmingham raw-sorghum program (completed, corpus standing). Bajomo & Young's 1992–1994 trilogy: profile, extract, fermentation — the full-replacement question answered in sequence at one school. The trilogy's close · Verified 2026-08-25
The Heriot-Watt sorghum program (completed, corpus standing). The Edinburgh school's commercial-enzymes-on-sorghum campaign — the application chemistry that framed the field's product classes. The record · Verified 2026-08-25
The UFRGS gluten-hydrolysis project (funded, active). A real grant with a number: Brazil's CNPq (process 405418/2021-3) and FAPERGS fund the Porto Alegre work applying enzymes across brewing stages and measuring residual gluten — the one currently grant-funded enzyme-application brewing program we have found, on this wing's boundary side. The funded study, open access · Verified 2026-08-25
The honest count, restated: six entries — two funded programs, one open proposal of ours, and three completed corpora standing. We have found no currently funded project anywhere whose named object is added-enzyme use in gluten-free brewing. The field's open questions have no sponsor — they live in this page's Research gaps as this site's asks.
4. Funders & Programs — who pays for applied enzyme research (described, never endorsed)
Novonesis R&D. The largest producer's self-funded application development — the handbooks, technical sheets, and named application scientists behind the portfolio this wing maps. The producer · Verified 2026-08-25
dsm-firmenich R&D. The second major's own development program — Brewers Compass and Clarex are its outputs, industry money answering industry questions. The producer's brewing line · Verified 2026-08-25
IFF R&D. The third major's brewing-enzyme development, reaching US craft through its distribution channel — the Amylex line among its outputs. The channel · Verified 2026-08-25
The Novo Nordisk Foundation. The ownership layer above the largest producer: the foundation's holding company is, by its own account, the controlling shareholder of Novonesis — the enzyme industry's biggest player is, at its root, foundation-anchored. Novo Holdings · Verified 2026-08-25
The Carlsberg Foundation. The brewing world's oldest research funder: a fixed 8% of its annual grants goes to the Carlsberg Research Laboratory — founded 1875 — the same laboratory that brewed our fonio directory's 100% fonio beer. The foundation's laboratory · Verified 2026-08-25
European Union framework programmes. The public money under the wing's academic backbone: the UCC program that produced the unmalted-sorghum corpus counts thirteen EU-funded projects across its portfolio. The funding record · Verified 2026-08-25
Ireland's national funders. The same record's other half — forty-seven national grants behind the Cork program whose corpus anchors this wing's literature. The record · Verified 2026-08-25
Pennsylvania's malt and brewed beverage program. A US public funding line whose supported work touches this wing: the Penn State program's modified mashing operates in the enzyme-supported gluten-free space, alongside USDA-NIFA support named on the same work. The program · Verified 2026-08-25
The honest shape of it, held under the count: eight entries — but three are the industry funding itself, and two are ownership rather than grants. Public money still does not, in anything we have found, reach the added-enzyme layer that commercial gluten-free brewing actually runs on as its named object.
5. Suppliers & Industry — who makes and sells the enzymes
Described, never endorsed — a listing is a map reference, not a recommendation, and dose or product choices belong to a brewery's own trials against technical sheets.
— The producers —
Novozymes (Novonesis) — Denmark. The industry's largest enzyme house, with a named brewing portfolio spanning the classes this field uses: high-temperature alpha-amylase (Termamyl), amyloglucosidase (AMG), fungal alpha-amylase (Fungamyl), multi-enzyme cereal blends (Ceremix), attenuation tools (Attenuzyme) — and Ondea Pro, the raw-grain package built for 100% unmalted barley, a boundary this site maps but does not cross.

The Craft Brewers Conference. The US industry's trade floor — the annual event where the enzyme suppliers' booths meet craft brewing, gluten-free brewers included. The conference · Verified 2026-08-25
The gap, stated carefully: we have found no organization or event dedicated to enzymes in gluten-free brewing specifically — the topic convenes inside the brewing-chemistry meetings and the enzyme industry's own technical channels.
7. Regulation & Labeling — the rules added enzymes answer to
Regulation lives on this side of the enzyme wing because it applies to what a brewer adds — not to what a seed does on its own.
The processing-aid classification. The frame everything below hangs on: brewing enzymes are expected to be inactivated or removed in manufacturing, so they are treated as processing aids rather than label ingredients — the reason a beer's enzyme program is invisible to its drinker. FDA's enzyme-preparations guidance · Verified 2026-08-25

TTB's approved adjuncts. The alcohol regulator's own list: TTB maintains approved adjuncts for beer, including enzyme processing aids — the federal permission structure specific to brewing. The list · Verified 2026-08-25
The gluten-reduction boundary. The enzyme this wing must name without using: prolyl-endopeptidase preparations (Brewers Clarex the best known) degrade gluten in barley beer — the basis of "gluten-reduced," which this site's first principles hold apart from gluten-free. On this directory's map it is a boundary marker: the most commercially successful enzyme in the gluten conversation, serving the approach this site exists as an alternative to.

How the field connects — documented links between the entries above
Every connection below is documented — no inferred relationships, no speculation.
This wing is the site's own process. Gluten Free Brewer's position assigns conversion to the products this page maps — and the site's protocol and method pages document them in use. Uniquely in this directory, the mapping site is itself a worked example. The position · the protocol
Arendt on both wings. The UCC program anchors the family's malting science — and wrote the unmalted-sorghum-plus-enzymes corpus. One group holding the strongest hand on both sides of the enzyme ledger. The added side
Łódź on both wings too. The quinoa page's brewing scientist tested the added-enzyme route on unmalted pseudocereals — the same lab appearing in this wing and the internal one. The study
Desobgo, twice. The sorghum directory's modelling specialist wrote this wing's dose-optimization mathematics — one researcher connecting the grain family to the enzyme wing's most practical question. The modelling
The distributor the site already names. Gusmer — IFF's exclusive US brewing-enzyme channel — appears on this site's own method pages; the supply chain this wing maps runs through pages this site published first. The distribution · our method page
The raw-grain packages point at barley. The two flagship full-replacement products — Ondea Pro and Brewers Compass — were built for unmalted barley brewing. The most developed corner of this wing's market serves the one grain family this site will never brew: a boundary, mapped. Ondea Pro's design · Brewers Compass
One measurement vendor, both wings. Megazyme's kits quantify what malt makes and standardize added activity — the assay layer is shared infrastructure between this page and internal enzymes. The kits
The unmalted outer ring runs on this wing. Fonio ships to brewers unmalted, quinoa arrives flaked, and both routes assume added conversion — the newest grain pages' commerce presumes exactly the products this page maps. The fonio product · the quinoa product
The invisible ingredient. Processing-aid classification means the enzyme program that converts a gluten-free beer never appears on its label — the regulatory frame that keeps this whole wing out of the drinker's sight. The frame
The boundary product outsells the category. Brewers Clarex serves gluten-reduced barley beer — the approach this site's first principles reject — yet it is the gluten conversation's most commercially visible enzyme. The map must include the road this site doesn't take. The product · our position
The position's own footnotes are this map. The site's external-enzymes doctrine cites Bajomo, Muoria, and Taylor as its published evidence — three names now carrying entries across this wing and the internal one. The directory didn't import the doctrine's sources; it found them independently and met them there. The position's citations, in context
The catalog is the census. No public record shows what the industry uses — except the distributor's own published catalogs, which quietly document what can be bought. The gap section's invisibility problem has one paper trail, and it's a sales document. The catalogs
EFSA papers the invisible. The processing-aid frame keeps enzymes off labels, but the EU's safety evaluations put the same preparations into the open literature — the regulatory geography where this wing's products are most publicly documented. An evaluation
Birmingham's FAN floor meets the yeast's needs. The trilogy fermented at 51 mg/L FAN — far below barley's conventional floor — the exact tension this site's own yeast-nutrition guidance manages in practice. A 1994 finding and a working page, thirty years apart, on the same number. The 1994 study · our guidance
One Nsukka unit owns the modern corpus. The 2016 malted-plus-enzymes study and the 2020 sugar-balance work both came from Okolo's brewing unit — the field's newest academic thread runs through a single named Nigerian laboratory. The unit's 2020 study
The producers speak through MBAA. Aastrup's enzymes-in-brewing deck was a Master Brewers presentation — the industry's application knowledge reaches working brewers through the technical association's podium, not the journals. The deck (PDF)
Carlsberg's laboratory closes a century's circle. The 1875 foundation-funded laboratory that professionalized brewing science now brews this family's grains — the institution at this wing's historic root is also at its newest frontier, on our fonio page. The laboratory
Ask 6's method already exists. The dose-reduction study this site keeps asking for has its mathematics waiting on this very page — Desobgo's response-surface modelling is the tool; what's missing is only the funded run. The ask · the method
Denmark holds both ends. The foundation controlling the largest enzyme producer and the foundation funding brewing science's oldest laboratory are both Danish — one small country's philanthropic structures bracket this wing from product to science. The producer's owner · the laboratory's funder
The site iterates its own wing. Mash Protocol 1 is the position in production; Mash Protocol 3 is its proposed successor — the enzyme sequence redesigned toward a conventional wort. This wing's mapping site doesn't just use the products; it publishes its own next experiment. The protocol · the successor
The 2002 finding is the table's first row. Goode & Arendt found a heat-stable α-amylase essential to unmalted-sorghum saccharification; this site's enzyme-class table opens with exactly that class — a twenty-year-old bench result living on as a working page's first line. The finding · the table
One enzyme, every scale. Amyloglucosidase ships as Novozymes' AMG in industrial volumes and as White Labs' Ultra-Ferm in 10 mL homebrew vials — the same class, from tote to teaspoon, spanning this wing's whole market. The industrial form · the vial
Research gaps — where the field's coverage runs out
The dose question is unpublished. Every gluten-free brewery running added enzymes has dose data; we have found no published, systematic dose-reduction study against measured conversion targets. That is this site's Research Ask 6, still open — and its companion, Ask 7, asks the same discipline of the 190°F mash baseline.
The application literature is sorghum-heavy — and our first claim about millet broke on checking. An earlier version of this note said millet had almost no added-enzyme literature; a wider sweep found the granule-degradation microscopy, the 2020 sugar-balance study, and the 2025 adjunct work, and they are now in this page's literature. What survives the correction: the corpus still centers on sorghum, much of it predates the modern gluten-free industry, and no added-enzyme study we have found addresses the malted-millet-based grists US gluten-free brewing actually runs on.
No public funder touches the wing. The funding section's honest shape, restated as the gap it is: the products carrying commercial gluten-free brewing are developed entirely on private R&D, and the open questions have no sponsor.
Gluten-free-specific product guidance is scarce. The producers' technical sheets address barley brewing and general adjuncts; we have found no producer publishing application guidance written for gluten-free grists specifically.
The processing-aid frame hides the data. Because enzymes never reach the label, no public record shows which products the industry actually uses at what rates — the same invisibility that protects proprietary process also starves the field of shared knowledge.
Run an enzyme company, program, or project we should list? Entries are added on merit once verified — tell us about it.
Entries are added as they are verified, never to pad the count. A listing here is a map reference, not a citation: this directory deliberately maps the added-enzyme world relevant to gluten-free brewing — a wider circle than the specific evidence our brewing guidance is built on, which every guidance page cites directly.
